GDZRS series Winding DC resistance tester is optimal designed for measuring three phase winding DC resistance of big capacity transformer. It can test three phase winding DC resistances at the same time

The PT-1 provides a simple and easy way to determine the relative polarity of coil windings. It allows for an in-process test that takes a minimum of time to perform. By placing a coil on the platform and making connection to the start and end of a winding, a test signal is induced in the winding.

The FRAnalyzer detects defects in power transformer windingsand faults in the magnetic core. After the transport oftransformers to site and following through faults with highcurrents the frequency response test should be made to ensure that the windings were not damaged.

Surge testers (impulse winding tester) is used for testing and check the insulation grade of turns between turns, insulation grade of layers between layers, insulation grade of windings between turns. Ultra High 5000V Test Voltage.

This instrument is used to check the correctness of polarity markings on transformers. In operation, the two leads carrying the test current are connected to one of the transformer windings. The other two leads from the indicating meter are connected to the other winding.

AJIT Transformer Ratio Meters are the most modern turn’s radio meters widely used to test the turn’s ratio of high voltage windings, to low voltage windings, of Transformer. These meters are accurate, compact & light in weight.

The 7720 Impulse Winding Tester uses a very high voltage impulse to stimulate the device under test (DUT). It analyzes the decay waveform to detect changes in material, shorted and damaged windings and other errors. Long term decay of a winding can also be detected.

This test set provides a continuously variable output voltage at double frequency to test the insulation between turns of coils, layer to layer, terminals of windings with either uniform or graded insulation and also between the windings and earth, with graded insulation of both Distribution and Power transformers.
